"The True Discoveries of Witches and Demons is the second release by Zorn's heavy new organ trio of John Medeski, Matt Hollenberg and Kenny Grohowski. Described as Tony Williams' Lifetime on steroids, here they are joined by special guests Marc Ribot and Trevor Dunn to make the music even heavier and more intense. This is white hot, mind bending music filled with heavy riffs, fiery solos and improvisational madness. Three generations of musical explorers come together to rip your mind to shreds in the second installment from Zorn's heaviest new ensemble Simulacrum."-Tzadik
